Freescale Semiconductor Technical Data
Heterojunction Bipolar Transistor Technology (InGaP HBT)
High Efficiency/Linearity Amplifier
The MMA20312B is a 2--stage high efficiency, Class AB InGaP HBT amplifier designed for use as a linear driver amplifier in wireless base station applications as well as an output stage in femtocell or repeater applications. It is suitable for applications with frequencies from 1800 to 2200 MHz such as TD--SCDMA, PCS, UMTS and LTE. The amplifier is housed in a cost--effective, surface mount QFN plastic package.
Typical Performance: VCC = 5 Vdc, ICQ = 70 mA, Pout = 17 dBm
